Why I'll Never Be Thinner

Every day I'm reminded that not only to lose but to maintain any weight loss you have to treat it as your full time job. From a post on the McDougall forums:

People tell me that I am lucky to be slim.There is no luck about it. I have worked hard over the years to keep my weight as a lower level. That is hard work, week in and week out. I have only rarely let my hair down and that has led to me gaining these pesky eight pounds.

This is why I will never lose weight. I'm too . . . well, I was going to write "lazy" but I'm not, really. In the past I did do all the right things that should have lead to weight loss, but they never worked. I would lose a few pounds - much less than the plan promised and in a much longer amount of time - and while still working the program the weight would start to come back on. "Eat less and exercise more." Well, I was already eating less than 1000 calories a day and exercising for an hour on top of working 8 to 16 hours in a strenuous job and taking doctor prescribed amphetamines appetite suppressants. How much more was I expected to do? I'm now 30 years older and 50 pounds heavier. Now what am I supposed to do?

Learn to accept myself as I am and tell the doctor who wants me to somehow magically get down to a weight I couldn't even sustain when I was 10 years old to go stuff it in his stethoscope, I guess. But how?
